ABORT switch while recording is in progress. Pressing it when recording has already
stopped will not work. If memory is low and the undo buffer is disabled, you may not
be able to abort playback or recording. In this case, the ABORT switch appears gray.
First Mix Scene
Each automix starts with a mix scene recall event that recalls the first mix scene. The
first mix scene sets the mix settings as required at the beginning of an automix. Without
the first mix scene, mix settings would remain the same as when automix playback was
stopped.
When a new automix is created, the mix scene last stored or recalled is automatically
selected as the first mix scene. You can select another mix scene as the first mix scene on
the Event Edit page. See Editing Events Off-line on page 193 for more information.
When a mix scene is recalled in an automix, the mix scene recall safe channel settings
are effective.
"Midnight Phenomenon" & Offset
The "midnight Phenomenon" refers to the discontinuity that occurs when a timecode
passes through midnight. As an automix can be offset, this is not a problem with the
03D. However, the 03D must determine whether a received timecode value refers to a
point before the start of an automix or to a point in the middle. For example, an auto-
mix runs from 23:00 through midnight. Then, the 03D receives a timecode value of
22:30. That could be interpreted as either 22:30 before the automix start or 22:30 after
the start. The 03D uses the following method to determine the correct point: If the
received timecode value is within one hour of the automix start (00:00:00.00 or offset
value), it is interpreted as being before the automix start, and the first mix scene is
recalled. Otherwise, it's interpreted as being after the start point and the automix is
played from that point.
Note: If you start recording at a time before the specified offset, the offset setting is auto-
matically moved to an earlier point so that the mix adjustments can be recorded. The time
positions of existing events, however, remain the same.
